摘要： An image sensor includes a pixel array including at least one active pixel and at least one line-optical black (L-OB) pixel arranged in a matrix including first to nth rows and first to mth columns, the pixel array configured to output a pixel signal and a dark-level offset signal in units of columns during a read-out operation in one of the first to nth rows; a row driver configured to output a selection control signal to the first to nth rows; and an analog-to-digital converter (ADC) block configured to digitize the pixel signal and the dark-level offset signal. In the pixel array, a dark-level offset signal is simultaneously output from an L-OB pixel in another row during the read-out operation in one of the first to nth rows. Here, ‘n’ and ‘m’ each denote an integer that is equal to or greater than ‘2’.

摘要： An image sensor includes multiple counters and a counter controller. Each counter of the multiple counters is configured to perform counting of a comparison result signal and to generate a count result, the comparison result signal being obtained by comparing a ramp signal and a pixel signal of a column of multiple columns. The counter controller is configured to generate and transmit a counter clock signal and (n−1) delay clock signals to the counters, respectively, “n” being a natural number equal to or greater than two. Each delay clock signal of the (n−1) delay clock signals is obtained by delaying the counter clock signal by a corresponding offset code.
